stick welding open root

04-24-2013, 08:51 PM

I am in my 3rd week of stick welding and having trouble getting consistent penetration on the bottom side. Instructor has us doing our root pass with 6010 3/32 electrode flat position. Any help or tips?

Ok. So open root 1G. This is how I do it. So I will start with the prep for the weld. First thing I do when I'm testing is clean the whole plate both sides and the bevel and make sure before you put your land on that it is straight.... it super sucks to have an uneven gap.... you need you fit up to be the best it can possibly be for a test.

After I make sure my plates are **** near perfect I clamp them to somthing and put a 3/32 land on them both then recheck to make sure they are straight. The next thing I do is get a piece of Tig wire fold it into a bend to gap my plates. I also gap it at 3/32.

Next I lay my plates flat on the table to get it tacked together. The first tack I put in at 3/32. The next I gap at 1/8 in and it usually pulls when I weld it to right at 3/32. Everyones different though...... Dont get in a hurry... is this helping at all... I'll keep going.

After you have both tacks in flip your plate over and you will need to prep your tacks, basically your grinding them out thata way there is a knife edge on the startup spot and the ending spot. The reason you do this is because if you dont you will have incomplete fusion.

After you have your tacks ready its time to test.... ask questions... does this gap look good, is my land even, just incase.... two heads are better than one. What temp did you run yours at before I continue.

I keyhole mine I will start out Left and move to the right. When I start out its usually around 95amps. When I starton my tack I make sure as I move ove the edge of the tack that I blow through the part I knife edged. That makes sure that its tied in. After that I use whipping motion to from the left to the right, I just make sure that I watch my weld to insure that the keyhole stays open as you go to the right you look for that keyhole to open up. When it does you move back to the left to put some more of your weld in and just do it at a consistant pace.
